So I think this topic has been hit a few times, but I had a question which led me to something else.

So first up, .30g Bioval BBs... Has anyone used them? Yay or nay?

Second. Bioval .27 BBBMax BBs. I'm sure you guys know these are banned in some places, mostly just indoors. Why you might ask? Because they are not your average BB. Contrary to Bioval's statements these are made of GLASS. Or if by some feat of science they are not glass, they are as close as you can get to it. Basically the facts are; these have the same melting point and other boring statistics as glass. Chairmanlao shot aquarium glass with these, one shot, glass goes to pieces. A friend of a friend was breaking glass bottles with these, beer bottles, not some thin glass. I can't break those with an SR10 shooting 522fps with KWA .25s at point blank range. These are physically harder than bullet proof polycarbonate. Bottom line, they hurt, they break ****, if you can even find them I honestly wouldn't buy them. So that's my two cents. The reason I bring this up is actually just this past weekend someone brought a few of these and we shot some goggles with these... Needless to say the lens was destroyed on both sides in 2 shots. I found my "super-glasses" actually and tried these BBs on them... they did resist them and hold up fine. But keep in mind they are supposed to hold off 9mm solid steel projectiles at 100-some-odd mph. Not everyone has those and I only do because my mother is an optometrist. So guys just be careful with what you feed through your gun. Be mindful of what damage the BBs may cause the things outside the gun, not just inside of it. I'm pretty sure no one makes anything like these, but be careful anyway.

I've used Bioval .25's, .27's, and now .30's. The .25's are PERFECT for the MP7, shoots like a laser rifle to 150-200ft. The .27's are indeed crazy accurate and crazy hard, my friend shot the back window of his car out with 2 shots... ouch. I've only just started using the .30's in my brand new LM4 PTS so my results are still very subject to 'break in', but WOW I was impressed. It shot a solid 350fps and my range was outstanding with very consistent groupings, and people absolutely knew they were hit, they didn't even want to get shot a second time My 1911 PTP shoots great with .25's at 300fps, so no need to change that. I suppose this really depends on what gun you're using.

I bet that would work really well, given that gas guns like longer barrels and therefore can handle heavier BB's with said barrels. Do you mostly do indoor or outdoor games? I find that .25's give me my 'ideal' range outside, and of course inside it doesn't even matter.

For indoors, I like to go lighter...say.2's. Why? They get down range about 35 FPS faster and indoors the accuracy gained by heavier BB's isn't typically realized due to shorter engagment distances...and there's no wind....Go lightter indoors IMO.

Yeah for sure, if I had any real CQB fields here I would probably do the same. Also I'm fairly sure those Bioval .27's were made for law enforcement/training use specifically, so they probably weren't too worried about the destructive properties. Nobody has ever told me not to run them so... maybe? I dunno I'm happy with the .30's though.

Are they more accurate than KWA .30's?
I would like to try these .27's at the range, not for fielding.

Haven't done a true head-to-head but IMO yes. I have some. If the weather ever gets good enough to do some real testing I plan on doing a BB/hop-up test. Got a few mods I am going to try. After all, I've got my M4A1 tuned in all other areas e.g., FPS, ROF, furniture ($$$ - in fact I almost started a thread to see how much people have spent on their KWA's but thought better of it....perhaps it would be too much bragging/vulgar? - what do you think?)

Anyway, with any luck come spring I will post some range and accuracy data with KWA .2's, .25's, .3's and the Bioval BBBMax .27's along with the Bioval .25's. I am planning a few variations on hop-up mods all with carbine length barrels, approx 450 FPS (.2 bb). The two barrels will be the standard RIS vs the KM Head 6.02

Standard 2G bucking

Enhanced nub + 2g bucking

G&G green and standard nub

Flat nub with 2G bucking

Flat Nub with G&G green

Flat hop mod 2G

Flat hop mod G&G green

I am looking for 150, 175, 200, 225, 250ft, etc.

I'm thinking just to get the weather right it's going to be a PITA. This is what I would "LIKE" to do. If I can get 70-80% on a 2' x 2' target at 250 I'm stopping right then and there!....maybe, LOL

Now that is what I am talk'n bout !
Testing for your self to get to the facts.

To do all that you have planned will take more time than you think.
Could take all Summer to complete.
Your results will vary depending on if you are shooting in an open field (dealing with wind) or on a trail in the woods (no wind).
I may suggest a 300' measuring tape to know exact distances.
A scope will be helpful for shooting past 50 yards. Shooting for hours at a time will make your eyes squint like crazy using Iron Sights.
A gun rest will lead to better accuracy and save you from the fatigue of holding a gun for hours in a day.
Multiple barrels will make your over-all time needed for testing much shorter.
If you had two or three stock KWA 395mm inner barrels and the KM barrel, then that is four barrels you can test in one day.

$$$ Thread.
I don't think it is a bad idea.
There may be some bragging about the $$$ some have spent.
I don't think it will turn vulgar by definition or vulgar in a super snooty way, though one or two may post like that.

I really could not tell you how much money I have spent specifically on KWA.
I went way over the top when I got into airsoft.
I way over did it with number of guns, camo and loadout in almost every color, and everything else.
I was only able to do that because of credit cards and working two good jobs and making good money.

Most of what I do now is tech specific for reaching performance goals in all my airsoft guns, China Clones included. There are externals that I like, so that adds up along the way.
I know I have spent thousands on airsoft over the last five years.

I know I will not spend the money over the next five years that I have in the last five years.
Now, I don't want or need half the things I did previously.
My job situation has changed and my credit cards are maxed out.
That is due to the economy and not having enough business at work.

I had 11 guns.
Just sold all my AK's and parts for I am just not an AK-47 guy.
Now I have 7 guns and tons of parts.
I am about to sell off a couple of China clones.
I am trying to get down to my four KWA's and keep one China clone.
I am sure I could build a gun or two out of parts and sell them, so I will probably do that.
I have been selling off a ton of gear that I do not need and have never used.

I am simply trying to get down to simple basics of what I need and want most, nothing extra.
Gun performance through growing in tech skills is where my focus and money is at.
It has been nice to get some $$$ back from airsoft after having spent so much on it.
You know, making money on airsoft as opposed to always spending money on airsoft has made an impression on me.

I had the worst experience with Biovals recently. in my MP7 i'm not sure if I got a bad batch, loading incorrectly or what but I noticed 3 of my mags had broken BBs in them and caused the springs to jam up. had to slowly remove all the BBs and clean them out.

and i noticed the broken splinters in the top by the feed lips, that little opening on the side, wedged in were pieces.

Haven't had issues like that w/ Elite Force bbs yet.

That's very odd, my MP7 has been running white Bioval .25's for over a year with stellar performance.
